Hi,
In the editwizards, you can do stuff like this:
<optionlist name="newstype"
optionid="[EMAIL PROTECTED]'type']"
optioncontent="[EMAIL PROTECTED]'name']">
<query xpath="/[EMAIL PROTECTED]"/>
</optionlist>
This will fill an optionlist with name 'newstype' with 'type/name' values
from the 'newstypes' builder. Very handy if you don't want to manually
edit your editwizards every time a new newstype is invented.
The problem is that there is no way to do a multilevel search here.
Sometimes, you have newstypes related to a 'site' object; and you only
want to select those. This syntax doesn't allow it.
I would propose a small extension to the query syntax to allow multilevel
searches. After browsing the code a bit, I found the queryparsing code to
be 'getList()' in Dove.java:
if (xpath.indexOf("/*@")!=0) {
Element err = addContentElement(ERROR,"invalid xpath",out);
err.setAttribute(ELM_TYPE, IS_CLIENT);
} else {
//get node data, bit stupid
try {
NodeManager nm = cloud.getNodeManager(xpath.substring(3));
for(NodeIterator i=nm.getList(where,orderby,directions).nodeIterator();
i.hasNext(); ) {
....
There is no supporting code for multilevels in Dove as far as I can see,
but it could easily be added here. For instance by using syntax like:
/[EMAIL PROTECTED]/related/newstypes
Any comments?
